Curve of Saturation of the Magnetic Circuit.
A characteristic curve whose ordinates may represent the number of
magnetic lines of force induced in a magnetic circuit, and whose
abscissas may represent the ampere turns of excitation or other
representative of the inducing force.
Curve of Torque.
A characteristic curve showing the relations between torque, q. v., and
current in a dynamo or motor.
Curve, Permeability Temperature.
A characteristic curve expressing the changes in permeability of a
paramagnetic substance as the temperature changes. The degrees of
temperature may be abscissas, and the permeabilities corresponding
thereto ordinates of the curve.
Cut In. v.
To connect any electric appliance, mechanism or conductor, into a
circuit.
Cut Out. v.
The reverse of to cut in; to remove from a circuit any conducting
device, and sometimes so arranged as to leave the circuit completed in
some other way.
Cut Out.
An appliance for removing any apparatus from an electric circuit, so
that no more current shall pass through such apparatus, and sometimes
providing means for closing the circuit so as to leave it complete after
the removal of the apparatus.
